Please make sure that this is a bug.

System information

• OS Platform: linux
• Python version:3.9
• HyperGBM version: 0.3 or 0.2.5.7
• hboard: 0.1.1

Describe the current behavior if make_experiment() set down_sample_search=True and webui=True, hypernets will report the following warning, which results in invalid search steps.

bug已定位 文件路径：hypernets\experiment_extractor.py 在extractors中添加'SpaceSearchWithDownSampleStep': SpaceSearchStepExtractor。 如下所示： extractors = { StepType.DataAdapting: DataAdaptionStepExtractor, StepType.DataCleaning: DataCleanStepExtractor, StepType.FeatureGeneration: FeatureGenerationStepExtractor, StepType.DriftDetection: DriftStepExtractor, StepType.FeatureSelection: FeatureSelectionStepExtractor, StepType.CollinearityDetection: MultiLinearityStepExtractor, StepType.PseudoLabeling: PseudoStepExtractor, StepType.DaskPseudoLabelStep: PseudoStepExtractor, StepType.PermutationImportanceSelection: PermutationImportanceStepExtractor, StepType.SpaceSearch: SpaceSearchStepExtractor, 'SpaceSearchWithDownSampleStep': SpaceSearchStepExtractor, StepType.FinalTrain: FinalTrainStepExtractor, StepType.Ensemble: EnsembleStepExtractor, StepType.DaskEnsembleStep: EnsembleStepExtractor }
